PIPE-ORGAN.

'SPECIFICATION forming part of Letters Patent No. 626,415, dated June 6, 1899.

Application filed August 27, 1898. Serial No. 689,653. (No model.)

such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to pipe-organs; and it consists in certain improvements in the construction thereof,l as will be hereinafter fully described,and pointed outv inthe claims.

The invent-ion is illustrated in the accolnpanying drawings as follows:

Figure 1 shows a plan view of the air mechanism immediately adjacent to the pipes, the pipes being removed. Fig. 2 shows a section on lines 2 2 in Figs. l and 3. Fig. 3 shows a section on the lines 3 3 in Figs. l and 2. Fig. 4L shows an enlarged view of the pipe-valve. Fig. 5 shows a cross-section of said valve.

A marks the pipes, B the air-chamber below the pipes, and C the port-chamber between the pipes and the air-chamber B.

The air is admitted from the register-stops through the opening b to the chamber B, passes through the port c', through the valve E into the port-chamber c2 by way of the port c3, and then passes from the port-chamber c2 to the pipe A by way of the opening c4. The port-chest C is formed between the pipe-plates C and partition-plates C2 by means of'the cross-partitions e c. These partitions are so arranged as to providethe ports e and the port chamber c2 in their proper relations. The openin gs for the port c' are made through the pipe-plate C and partition-plate C2, and

.the port c3 and opening c4 are also provided in the plate C.

This invention relates more particularly to the peculiar construction and relation of the air-chamber B, port-chest C, valves E, and pipes A.

The valve E is formed vof a block e, which has provided in it the depression e. The valve-leather e2 is secured to the bottom face of the block, entirely covering the depression e. These valve-blocks are fastened on the top of the plate C', each adjacent to the pipe which it controls. The valve-leather e2 of the valve E covers the ports c' c3. This arrangement of the valves on the top plate C' makes them readily accessible, and each valve can be independently removed and repaired when repairing becomes necessary. This arrangement, in connection with the port-chest C, is also particularly advantageous, because by means of this chamber the several ports can be readily constructed, all leading to the same register-chamber B.

I have provided the following mechanism for operating the valves E: When a registerstop is operated, air under pressure is admitted to the chamber B and passing into the ports'o exerts pressure on the valve-leather e2. Normally an equal air-pressure is maintained above the valve-leather and this, by reason of the larger surface exposed above, readily seats the valve-leather and closes the valve E upon the port c. Passing from the cavity or depression e is au opening es, which in the valve-block is preferably L-shaped, opening at the bottom of the block. Passages e4 are provided in the side plates of the port-chest and register-chambers, extending through the same and communicating with the channel-duct e6, arranged at the bottom of the register-chambers. The duct e6 connects the ducts e4 of the different registers in the system. An air-chamber F is placed conveniently to the pipe mechanism and has supplied to it constantly air under pressure. A duct e5 leads from the duet e4 intothe port f, which port f communicates with the chamber F and also with the atmosphere. Valves f and f2 are arranged at the opposite ends of the port f on a stem f3. The stem f3 is carried by the upper block f4 of a bellows-motor F'. This bellows-motor is provided with the upper block f4, the flexible material, usually leather, f, and a lower block f5. These are usually formed by simply cementing the leather around the outer peripheries of the blocks f4 and f5. The valves f and f2 are arranged a sufficient distance apart so that when one closes the port-f the other of the said valves openssaid port j'.J A duct Fzleads from the bellows-motor F' to the key or pedal mechanism. An air-chamber G is provided near the key mechanism, in which is a valve g, which covers a port g2, leading to the duct F2. A spring g assists the air-pressure in ac- IOO leVY

' g4, and thus the valve g. As the valve g is raised the air passes YVthroughthe port lg2 and duct F2 to the bellows-motor F. The effect of this is to close the valve fi and to open the valve j". Upon the cpening of the valve f the valve-leathers of the several valves in communication with VVsaid valves f are immediately relieved of the air-pressure of the Ychamber F and the air from the chamber B Vforces up the leather e2 and immediately passes into the pipes. This action is almost instantaneous, as the valves E are opened immediately the valve f is opened. A port gs communicates with the port g2 and forms a passage-way for the stem g4. A valve G is arranged on this stem, so that as the pedal is operated to raise the stem g4 and the valve g the valve G closes the port g3, so that the communication with the atmosphere through the port g3 is cut off. When the key is relieved and the stem g4 is lowered by the action of the valve g, the valve G is openedand allows the air to escape from the bellowsmotor F. The bellows-motor has its upper plate f4 of larger arca than the valve f2, so that immediatelyas the motor is relieved of internal pressure this greater area of the top plate f4, together with the toggle-joint effect of the leather f6 under the action of the air, operates to move the valve-stem f3 and to thus close the valve f and te open the valve f2. This places the depressions e in communication with the air in the chamber F, and this pressure immediately forces the valveleather e2 down upon the port c', thus closing communication between the air-supply in the chamber B and the pipes.
